I am a DSLR shooter (though I began, briefly with a rangefinder over 30 years ago).

What I would like to know is how would I know best if I liked shooting with a rangefinder without the investment in Leica gear.

Also, assuming something hits on May 10th I would go for, what would people recommend as a "killer" 3-4 lens kit.

I will be traveling a lot in the next 2-5 years and would really like the best kit possible for that. I took the NEX-7 to Cuba with me this last December, and would love to leave my DSLR home from now on, as it is too cumbersome and draws too much attention.
